Trying to Install AfterMarket Radio... Wiring Help! *Did Search*
First off, this is for a 93 SC300 with the factory Pioneer stereo and could anyone tell me which 2 out of the 4 radio harness do i use? Also, for those people that had bought a radio adaptor harness from a 87+ toyota, could you tell me if you had any problems or had to rewire the harness? I was looking at the harness and stock clips, none of the color wires matches and there's extra ones on the adaptor harness. If could someone point me to the right direction to a 93 SC300 Pioneer radio wiring diagram, that would be great, i have this link that i found in the "search", but it's a little blurry and i cant make out the names... http://carstereohelp.net/wireharness_Lexus1.htm
Well here are the pics, please let me know which ones i will need to use and im trying to make sure i bought the right harness...

The image on that link is not really blurry. It's just a very big image so if you expand your browser, you will see more details. Or you can save the image on your drive then use an image viewer.

I dont remember which 2 of the 4 plugs i used. But to mee it looks like the blue plug you are using is for the sub and mute function? So i dont think thats the correct plug. But again i dont quite remember, as it has been a while since i installed my radio. I do know however, that none of the wite colors will match. Lexus/toyota doesnt use standard wire colors like all aftermarket radios. Just FYI.

Hey man, the middle connector on the bottom of your factory radio....you're right not to be using that one, it goes to the CD changer...
But, the one on the top, the connecter that goes in there runs to all of the speakers, so if you aren't connecting into that one that's one problem.
The blue one has something to do with "ac control switch and radio switch." I don't think you need that one but I'm not 100% sure.
I just downloaded the wiring diagram and I'm looking at it right now.

Ok this is way more confusing that the one in my GS. Damn.
Yeah I got the diag from intelluxual.net I think. Hold on I am going to print this thing and make some notes on there and probably scan it back in and post it here.

Connecter C
Everthing except ANT, ACC, and MEMORY go straight to the factory amp. The ones that aren't labeled must not do anything because there is nothing on the diagram to suggest otherwise.
This is the one up top on your radio.

Connecter A
This is the one you labeled ???? in your pic. Rightfully so. Some random stuff on here - going mostly to the woofer amp.
You've got the woofer signal and you have ANTA and ANTB. They have something to do with how Lexus antennas go up and down depending on the frequency on the radio staion you are listening to. If you ignore ANTA & B there is a good chance your antenna will not go up at all. Somebody figured this out in the past so I suggest you do a little search on that.
